The PVC pipe production line is a necessary large-scale machine and equipment for the production of PVC pipes. This machine and equipment can be produced in batches and is extremely efficient. However, it should be noted that the method of use must be correct, otherwise not only the product quality will not be guaranteed, but even the machinery and equipment may be damaged. The startup sequence of the PVC pipe production line is also very important. Let's learn about the correct startup sequence.
1. Before starting the production operation of the PVC pipe production line, it is necessary to preheat and raise the temperature, that is, turn on the main power switch and set the parameters of the temperature control instruments of each heating zone according to the process requirements. If the temperature of each section is normal and the temperature control instruments are working normally, wait until the temperature reaches the set value and then keep it warm for 2 hours.
2. After the temperature is constant, start the main motor of the plastic extruder to gradually increase the screw speed from low to high, and then open the hopper insert plate to discharge the material into the barrel.
3. Then observe the color status of the material discharged from the die mouth and the current value of the extruder, and adjust the temperature and speed according to the process needs. Then start the vacuum pump and spray water pump to adjust the vacuum degree in the box.
4. Connect the extruded pipe port with a guide tube, manually pull it to the clamping block of the tractor, start the tractor, and adjust the pulling speed to match the extrusion amount.
5. Adjust the air pressure of the cutting machine, set the length of the pipe, and put the cutting machine in the standby state.
